Description

The Aotoro EK51-D2M4 photoelectric sensor utilizes a diffuse reflective principle, where the emitter and receiver are housed in the same unit. It detects objects by measuring the intensity of light reflected back from the target surface, making it suitable for detecting a wide variety of materials and colors within its specified 2cm range. The sensor is engineered for industrial environments, featuring a robust housing that meets IP66 standards for resistance to dust and water.

Designed for seamless integration into control systems, it operates on a versatile 24V AC/DC power supply commonly found in factory automation. The unit includes a selectable Light ON/Dark ON mode, allowing it to be configured for either normally-open or normally-closed output logic based on the presence or absence of a detected object. Its compact form factor and included mounting accessories facilitate straightforward installation on machinery, conveyor systems, and automated equipment.

Key Features

  • Universal Power Input: Compatible with both 24VDC and 24-240VAC power sources, simplifying inventory and wiring in mixed-voltage panels.
  • Industrial-Grade Protection: IP66-rated housing provides excellent defense against dust accumulation and high-pressure water jets, ensuring longevity in harsh conditions.
  • Stable Detection Performance: High-quality optics and circuitry deliver consistent object detection with high immunity to electrical noise and ambient light interference.
  • Operational Flexibility: User-selectable Light ON or Dark ON operation mode adapts the output logic to suit specific application requirements.
  • Durable Construction: Engineered for continuous operation in industrial settings with an operating temperature range of -25°C to +60°C.
  • Optimized Form Factor: Compact design allows for installation in tight spaces without sacrificing sensing performance or environmental sealing.

Applications

  • Object presence verification on assembly lines and packaging machinery.
  • Part counting and positioning control on conveyor systems in manufacturing.
  • Door and gate detection for automated access control and safety interlocks.
  • Material handling equipment for detecting pallets, boxes, or components.
  • Level detection for non-transparent containers in process automation.

Frequently Asked Questions

What is the operating voltage range for the EK51-D2M4 sensor?

The sensor is designed for universal AC/DC 24V operation. It can be powered by a standard 24VDC supply or directly from a 24-240VAC line, making it highly versatile for integration into existing industrial control panels without requiring a separate power converter.

What does the IP66 rating mean for this sensor?

The IP66 rating indicates complete protection against dust ingress (first digit '6') and protection against powerful water jets from any direction (second digit '6'). This makes the sensor suitable for use in dusty environments, washdown areas, or outdoor applications exposed to rain.

How do I configure the sensor for Light ON or Dark ON operation?

The EK51-D2M4 features an internal switch to select between Light ON and Dark ON modes. Light ON means the output is active when the receiver detects the reflected light beam (target present). Dark ON means the output is active when the beam is blocked (target absent). Consult the product datasheet for the specific switch location and configuration procedure.

What types of surfaces can this diffuse reflective sensor detect?

This sensor can detect a wide range of opaque and semi-opaque materials, including plastic, metal, wood, and cardboard. Its performance is influenced by the color, texture, and reflectivity of the target surface; lighter and more reflective surfaces are typically detected at the maximum 2cm range, while dark, matte surfaces may require a shorter detection distance.
